Do B Vitamins Have An Impact On Brain Function

What are the uses of Vitamin B Complex?

Given that B vitamins are essential for every aspect of brain function, and that large proportions of the population of developed societies have less than optimal levels of vitamins, it would be expected that a relationship would be evident between vitamin consumption and mental function both in terms of epidemiological studies and controlled intervention trials. The driver for much of the research conducted to date in both of these domains has been the homocysteine hypothesis described above. Concentrating on this one unproven hypothesis has resulted in both observational and controlled trial research being focussed disproportionately on just three of the vitaminsfolate and vitamins B6 and B12. However, the observational and the controlled trial research concentrating on these three vitamins could be seen as generating somewhat different conclusions.

How We Select Supplements

Our team works hard to be transparent about why we recommend certain supplements you can read more about our dietary supplement methodology here.

We support supplements that are evidence-based and rooted in science. We value certain product attributes that we find to be associated with the highest quality products. We prioritize products that are third-party tested and certified by one of three independent, third party certifiers: USP, NSF, or ConsumerLabs. We also prioritize non-GMO, Organic, and products that are free of unnecessary and potentially harmful additives.

It’s important to note that the FDA does not review dietary supplements for safety and effectiveness before they go to market. Our team of experts has created a detailed, science-backed methodology to choose the supplements we recommend.

B Vitamin Deficiencies In Developed Societies

A general assumption tends to be made that the populations of developed countries have adequate nutrition, and are therefore free from deficiencies in essential micronutrients. In order to encourage adequate nutrition, governments typically define a set of dietary reference intakes or similar for individual nutrients. These always include something akin to the recommended dietary allowance, or RDA. These government figures describe the minimum daily intake of the specific nutrient that is considered to be sufficient to meet the nutritional requirement of the majority of the healthy population. However, meeting the requirements in this context typically refers to simply preventing chronic, nutrition related diseases or a disease state related to a specific deficiency of that nutrient .

Produces Red Blood Cells

Some B vitamins, particularly vitamin B12, play an essential role in the formation of red blood cells. Healthy red blood cells are needed to transport oxygen to every part of the body, and when there’s a vitamin B12 deficiency, the body will struggle to produce enough red blood cells, often leading to anemia.

Vitamins B2 and B9 are also needed for red blood cell production and growth. While vitamin B5 plays a role in red blood cell production, it also helps reduce the amount of cholesterol produced by the body. And vitamin B6, which is required for more than 100 different enzyme reactions in the body, aids in the formation of hemoglobin, which also allows red blood cells to carry oxygen through the blood.

How Much Vitamin B Should You Take

If you have a deficiency this is something that must be determined by your doctor. In a normal, healthy diet, you should be getting all of the compounds of it through what you eat. Your body will eliminate excess vitamins through your urine. There are certain cases where an excess of certain vitamin B compounds can cause health problems.

If you start taking a vitamin B complex supplement you may experience a stomach ache for the first couple days as your body adjusts to the increase of vitamins. This typically goes away but if it doesnt, make sure to talk to your physician. If you have any questions about how much vitamin B you should be taking, consult your doctor. The recommended daily intakes are:

  • B-1: 1.1 1.2mg
  • Scaly skin or cracks around the mouth
  • Tingling or numbness in the hands or feet

If you are experiencing more than a couple of these symptoms it would be best to consult your doctor. They can recommend having you tested to find the vitamins you may be deficient in.

Whos At Risk For Deficiency

Vitamin B Complex for Anxiety

Some conditions and your lifestyle can affect your body’s vitamin stores and increase the need for taking a daily B-complex vitamin to help ensure you maintain adequate levels of important nutrients. Alcohol abuse decreases absorption, so excessive drinking may lead to a deficiency. A vitamin-B deficiency can also be the result of ingesting a tapeworm from contaminated food that’s not fully cooked due to the parasite sapping the nutrients from your body.

Vegetarians or people on a strict vegan diet who eliminate animal products are often deficient in B vitamins, especially vitamin B12. Pregnant and breastfeeding women have an increased demand for B vitamins, particularly B12 and folate. Not getting enough of these vitamins can result in a deficiency and possible harm to a newborn baby.

What Is Vitamin B10

Vitamin B10 is an alternative name for the organic compound PABA, a white crystalline substance.

Its considered part of the vitamin B complex, although its not a vitamin nor an essential nutrient. Its found in brewers yeast, organ meat, mushrooms, whole grains, and spinach .

Your body can also synthesize the compound using certain bacteria in your gut. PABA then assists in the production of folate . Yet, the amount of folate produced is inadequate to meet your needs, so you need to obtain it from other dietary sources .

PABA is thought to benefit skin and hair when taken as a supplement. Its industrially produced and sold in pill, powder, extract, and topical application form .


PABA is an organic crystalline compound also known as vitamin B10, although its not truly a vitamin. Its found in some foods and produced chemically for lotions and supplements.

While there are several proposed benefits of PABA supplements, limited studies support these claims.

The Effect Of Vitamin Deficiency On Mental Health

Nearly 10% of the U.S. population has nutritional deficiencies, while 31% of the U.S. population is at risk for at least one vitamin deficiency or anemia.

Vitamin deficiencies can be caused by poor nutrition, vegetarianism, chronic alcoholism, post-gastrectomy surgery, pregnancy, and certain medications, among other factors or conditions.

The most common vitamin deficiencies include folate, vitamin B6, and vitamin B12, with a subclinical vitamin B12 deficiency affecting somewhere between 2.5% and 26% of the population, depending on estimates.

Unfortunately, many people dont know when theyre experiencing a vitamin deficiency. They may be experiencing physical and mental health symptoms, but are unsure of the underlying cause.

Vitamin B1 Is Important For Preventing Beriberi

B Complex with C &  Iron

The recommended daily intake of vitamin B1, also called thiamine, is 1.1 milligram for women over age 18, up to 1.4 mg for those who are pregnant, and 1.5 mg for those who are breast-feeding. For men age 14 and older, 1.2 mg per day is recommended, according to the National Institutes of Health.

Vitamin B1 plays a major role in metabolizing food into energy. B1 is found in whole-grain cereals, yeast, beans, nuts, and meats. Too little vitamin B1 causes beriberi, a disease affecting the heart, digestive system, and the nervous system. Beriberi is found in patients who are malnourished, and in those who are heavy drinkers of alcohol. Symptoms of beriberi include difficulty walking, loss of sensation in the hands and feet, and paralysis of the lower legs and it may even lead to congestive heart failure. People who consume large amounts of alcohol should take a vitamin B complex supplement to be sure they get enough B1. Also, taking any one of the B vitamins for a long period of time can result in an imbalance of other important B vitamins. For this reason, you may want to take a B-complex vitamin, which includes all the B vitamins.
